摘要：
A promising direction for quantum computation is the topological quantum computation, for which topological superconductivity is one of the physical platforms. Intensive theoretical studies have been carried out and followed by tremendous experimental efforts in the realization of topological superconductivity, though debates remain mainly because of the inadequacy of the convincing detection techniques. In this talk, we find in a certain group of platforms for realizing topological superconductivity, the critical field obeys the unique power-law temperature dependence with critical exponent 2/3. We then apply our theory in iron-based superconductor FeTe1−xSex (x∼0.5) and doped topological insulator Bi2Te2.7Se0.3.
